clob

We have a table in Oracle 11g with a varchar2 column. We use a proprietary programming language where this column is defined as string. Maximum we can store 2000 characters (4000 bytes) in this column. Now the requirement is such that the column needs to store more than 2000 characters (in fact unlimited characters). The DBAs don't like BLOB or LONG datatypes for maintenance reasons. The solution that I can think of is to remove this column from the original table and have a separate table for this column and then store each character in a row, in order to get unlimited characters. This tble

I am trying to retrieve an image stored as a CLOB in a Derby DB via a Worklight SQL adapter. I would like to do something similar to what was written up here: https://www.ibm.com/developerworks/community/blogs/dhuyvett/entry/jsonstore_revisited_in_worklight_v6_part_1_the_adapter?lang=en except for the referenced article the author is using DB2. Does anyone know how I can do this in Derby? Currently when I go to retrieve the image doing a SQL Select, the string returned is "IMAGE": "org.apache.derby.impl.jdbc.EmbedClob@2d236" I would also consider mysql as an alternative. Thanks for any

This is the sample of my code. The field FUNCTION_SCRIPT is a CLOB field (the only CLOB field) in my table IS_FUNCTION public void ReadFunction(string FName, out string fContent) { OracleCommand command = _connection.CreateCommand(); OracleTransaction transaction = _connection.BeginTransaction(); command.Transaction = transaction; command.CommandText = "SELECT TO_CLOB(TO_NCLOB(FUNCTION_SCRIPT)) FROM IS_FUNCTION where FNAME=:fName "; command.Parameters.Add("FName", OracleType.NVarChar).Value = FName; OracleDataReader odr = command.ExecuteReader(); int temp = odr.GetOrdinal("FUNCTION_SCRIPT");

I am using CFQuery to retrieve the CLOB field from Oracle DB. If the CLOB filed contains the Data less than ~ 8000, then I can see <CFQuery > retrieved the value ( <cfdump> the o/p), however If the value in CLOB field size is more than 8000 chars, then its not retrieving the value. in <cfdump> i can see the query retrieved as 'empty String' though the value exists in Oracle DB. I am using the Oracle Driver in CFadim console, enabled 'Enable long text retrieval (CLOB).' and 'Enable binary large object retrieval (BLOB). ' Set 'Long Text Buffer (chr)' and 'Blob Buffer(bytes) ' values to 6400000

From these two threads, Why is LONG an issue with Oracle? Is it possible to read a CLOB from a remote Oracle database? LONG is archaic and deprecated. Oracle says , Do not create tables with LONG columns. Use LOB columns (CLOB, NCLOB) instead. LONG columns are supported only for backward compatibility. Oracle also recommends that you convert existing LONG columns to LOB columns. LOB columns are subject to far fewer restrictions than LONG columns. Further, LOB functionality is enhanced in every release, whereas LONG functionality has been static for several releases. But you cannot read a CLOB

I want to extract the value of Decision using sql from table TRAPTABCLOB having column testclob with XML stored as clob. Sample XML as below. <?xml version="1.0" encoding="UTF-8"?> <DCResponse> <Status>Success</Status> <Authentication> <Status>Success</Status> </Authentication> <ResponseInfo> <ApplicationId>5701200</ApplicationId> <SolutionSetInstanceId> 63a5c214-b5b5-4c45-9f1e-b839a0409c24 </SolutionSetInstanceId> <CurrentQueue /> </ResponseInfo> <ContextData> <!--Decision Details Start--> <Field key="SoftDecision">A</Field> <Field key="**Decision**">1</Field> <Field key="NodeNo">402</Field>

listagg is a function introduced in Oracle 11.2! now this function is bugging us allot, we are migrating from MySQL to Oracle and we have this query: SELECT p_id, MAX(registered) AS registered, listagg(MESSAGE, ' ') within GROUP (ORDER BY registered) AS MESSAGE FROM umm_parent_id_remarks_v m GROUP BY m.p_id; is works fine in MySQL as far as we know what bugging us is under Oracle it returns VARCAR and not CLOB as we need! the text is huge and we do need it to be CLOB ! here is what I tried to do! create a CLOB_T table of CLOB Type! then create the function create or replace function
